Microchip PIC18F25K80T-E/MM: A Comprehensive Technical Overview
The Microchip PIC18F25K80T-E/MM represents a robust and versatile 8-bit microcontroller within Microchip's extensive PIC18F K-series family. Housed in a compact 28-pin QFN (MM) package, this device is engineered for applications demanding high performance, low power consumption, and a rich set of integrated peripherals. It is particularly suited for automotive, industrial, and consumer applications where reliability and functionality are paramount.
At the core of this microcontroller is an enhanced PIC18 architecture with a 16-bit instruction set. Operating at a maximum frequency of 64 MHz, it can execute most instructions in a single clock cycle, delivering a peak performance of 16 MIPS. A significant feature is its wide operating voltage range (2.0V to 5.5V), which allows for flexible power supply design and enables operation in low-voltage, battery-powered scenarios.
The device boasts a substantial 80 KB of self-read/write capable Flash program memory and 3,792 Bytes of RAM. This generous memory allocation supports complex program structures and data handling. A key highlight is the inclusion of 1,024 Bytes of Data EEPROM, providing reliable non-volatile storage for critical data without requiring external components.
Its peripheral set is comprehensive and designed for embedded control. It features multiple communication interfaces, including:
EUSART: For serial communication (e.g., RS-232, RS-485).
MSSP (SPI/I²C): For interfacing with serial peripherals like sensors and memory chips.
AUSART: An addressable universal serial interface.
For analog needs, the microcontroller integrates a 10-bit Analog-to-Digital Converter (ADC) with up to 21 channels, facilitating precise measurement of multiple analog signals. It also includes two analog comparators for quick, responsive voltage comparisons.
Control applications are well-served by its CCP (Capture/Compare/PWM) and ECCP (Enhanced Capture/Compare/PWM) modules, which are essential for motor control, power conversion, and generating precise timing signals. Furthermore, it offers hardware capacitive voltage divider (CVD) support for advanced touch sensing implementations, making it ideal for building modern user interfaces.
The nanoWatt XLP (eXtreme Low Power) technology is a cornerstone of its design philosophy. This technology enables exceptionally low power consumption in all modes of operation (Run, Idle, and Sleep), which is critical for battery-powered and energy-harvesting applications.
Designed for resilience in harsh environments, the PIC18F25K80T-E/MM offers high noise immunity and a robust ESD protection rating. Its extended temperature range (-40°C to +125°C) ensures stable operation in demanding industrial and automotive conditions.
ICGOOODFIND: The PIC18F25KK80T-E/MM is a highly integrated and power-efficient 8-bit MCU. Its blend of substantial memory, a rich peripheral set, nanoWatt XLP technology for ultra-low power operation, and robust construction for industrial environments makes it an exceptionally flexible and reliable solution for a vast array of embedded control applications.
